Three months of heat, then a long stretch of idle
Lindenhurst runs its air conditioners June through August, with summer afternoons averaging 80°F. That is a short season, but a new system still has to be sized to handle it and then sit unused the rest of the year.
The area also sees real wind and hail. Over the past ten years there have been 434 damaging wind events and 17 hail events, with stones up to 1.75 inches. An outdoor condenser installed here needs to be secured with that in mind. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2.

A higher-efficiency unit would save about $30 a year to run in Suffolk County compared with a new unit at the federal minimum.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, ceiling height, insulation, window count and orientation, not just a rule of thumb per square foot. A contractor works this out with a load calculation, which looks at your actual walls, windows and layout rather than guessing from house size alone. Too big and the unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. Too small and it runs constantly through the summer without ever catching up. A contractor can size it correctly for your house.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing only the outdoor unit can cause problems. The two are matched at the factory to work together, and pairing a new condenser with an old coil can mean the system never reaches its rated efficiency, and in some cases the manufacturer won't warranty the mismatch. If both are old, replacing them together makes more sense. A contractor can look at the condition and age of each piece and tell you whether a partial swap will actually work here.
- Do HVAC contractors in Lindenhurst need a state license to work on my home?
- Ask to see a contractor's license before any work starts, and confirm it covers the specific work being done, whether that's installation, refrigerant work or electrical connections. A licensed contractor also carries the insurance that protects you if something goes wrong during the job. If you are not sure what license applies to your job, a contractor can tell you what they hold and what it covers.
